Filed June 11, 1964, Ser. No. 374,406 3 Claims. (Cl. 222484) Thisinvention relates to pouring spouts for bottles and particularly liquorbottles and more particularly to a pouring spout which does notinterfere with the closure of the bottle by the usual screw cap.

The principal object of the invention is to provide a pouring spout forbottles comprising a base element which may be fitted into the neck of abottle in the manner of a cork and which includes an air inlet tube andan extendable pouring spout and which, further, while installed in thebottle, does not interfere with the closure of the bottle by the usualscrew threaded cap.

Another object of the invention is to provide a pouring spout of theforegoing character and which additionally is capable of such economicalmanufacture that it may be regarded as a disposable item.

With the foregoing objects in view, together with such additionalobjects and advantages as may subsequently appear, the invention residesin the parts and in the con struction, combination and arrangement ofparts described, by way of example, in the following specification of apresently preferred embodiment of the invention, reference being had tothe accompanying drawings which form a part of said specification and inwhich drawings:

FIG. 1 is a perspective view of a pouring spout device constituting apresently preferred embodiment of the invention with the spout componentthereof being extended as for use,

FIG. 2 is a top plan view of the device shown in FIG. 1 having referenceto the attitude of the device as shown in FIG. 3.

FIG. 3 is a medial sectional view taken on the line 33 of FIG. 2 withthe spout retracted to permit the closure cap to be applied to thebottle as indicated in broken lines,

FIG. 4 is a medial sectional view similar to FIG. 3 but with the spoutcomponent extended for use,

FIG. 5 is a sectional view taken on the line 5-5 of FIG. 3, and

FIG. 6 is a perspective view of a bushing accessory usable with thedevice to vary the rate of discharge of fluid through the pouring spout.

Referring to the drawings, the illustrated embodiment of the inventioncomprises a base element 1, a pouring spout component 2, and an airinlet tube 3. The base element 1 is preferably molded from a somewhatrubberlike plastic such as, for example, a suitable grade ofpolyethylene or equivalent material and comprising a cylindrical skirtportion 4 adapted to fit yieldingly tightly into the neck N of a bottleB, a thin circular head flange portion 5, adapted to engage the end of abottle neck and provided with a shallow annular recess 6 of a diametergenerally similar to the inner diameter of the skirt portion 4 andseparated from the skirt portion 4 by an integral cross wall 7.

Closely adjacent to the inner wall face of the skirt portion 4, thecross wall 7 is provided with a bore 8 in which the air tube 3 istightly fitted and secured by any suitable means. The air tube 3 may beof any suitable material and conveniently may be formed of a suitablelength of extruded plastic tubing of sufiicient rigidity not to collapsewhen fitted (as by a force fit) into the bore 8. The tube is preferablyof such length as to extend at least substantially the entire length ofthe bottle neck and into the body portion of the bottle itself asindicated in FIGS. 1, 3 and 4.

The pouring spout 2 is also preferably formed of a plastic of the samegeneral characteristics as the base element 1 and comprises a short,curved tube preferably formed with a circumferential bead 9 at the outerend thereof. The spout fits tightly but slidingily in a hole 10extending through the cross wall 7 and after insertion into the hole 10,the inner end of the pouring spout is flared outwardly, as at 11, by anyappropriate means, as for example, by the point of a heated tool, toprovide an enlargement sufficient to prevent the tube from being removedfrom the base element 1. Since both the base element and the spout areformed from yieldable material, they will yield sufiiciently to permitthe curved portion thereof to pass back and forth through the hole 10 tothe extent permitted by the bead 9 and the flared inner end 11.Preferably, the spout component adjacent the bead 9 and the flared end11 is straight to conform to the axial line of the hole 10 to provide atight fit when in either of the two positions it occupies.

Referring to FIG. 3, it will be noted that the head flange 5 is nogreater in diameter than the outer diameter of the closure cap threadswhich engage the threads on the bottle neck, wherefore, the usual screwcap closure means C may be applied to close the bottle, the cap servingto press the flange 5 tightly against the end or" the bottle neck andthus the flange serves also as a gasket eliminating the gasket usuallyassociated with screw caps. Also it will be noted that the bead 9 fitswithin the recess 6 and is of such length as to be firmly seated on thebottom of the recess by the pressure of the cap on the outer end of thetube. Preferably, the bead 9 includes a tab element 12 projectingradially therefrom offering a gripping means for pulling the spout outfor use. For those uses in which it is desired to dispense fluid orliquor through the pouring spout at a slower rate, bushing elements suchas shown at 13 in FIG. 6 may be inserted in the inner end of the pouringspout.

Thus there has been provided a pouring spout arrangement for bottlesfrom which the contents are dispensed in small amounts and in whichsplashing due to the intermittent entrance of air is to be avoided andwhich is of such economical form that it can be provided with theindividual bottles and thrown away with them.

While in the foregoing specification there has been disclosed apresently preferred embodiment of the invention, the invention is not tobe deemed to be limited to the precise details of construction thusdisclosed by way of example, and it will be understood that theinvention includes as well, all such changes and modifications in theparts and in the construction, combination and arrangement of parts asshall come within the purview of the appended claims.
